This invention relates to oil burners of the type wherein a pressure fluid, such as steam is used in conjunction with the fuel oil and the primaryobj ect of the invention is to provide'a highly efflcient oil burner constructed to present novel outlet ports which combine to effectively act upon the .fuel oil immediately prior to combustion.

One of the primary objects of the invention is the provision of an oil burner having a plurality of outlet port holes communicating with oil and pressure fluid supply passages, which coact to effectively atomize the fuel oil.

An even furthercbject of the instant invention is to provide an oil burner which has a series of radially disposed outlet port holes for both the oil and pressure fluid passing from said burner.

A yet further object of the present invention is the provision of an oil burner having a series of radially extending port holes for both the pressure fluid supply and oil supply which port holes terminate in spaced apart arcuate planes; an arcuate converging slot being disposed by the said series of outlet port holes in a manner to cause them to effectivel dlrect the flow of ressure fluid toward the series of outlet port holes through which.

the oilsupply is passed.

Further objects of the invention will appear during the course of the specification referring to the accompanying drawing wherein an oil burner embodying but one form of the invention is illustrated. In the drawing:

Figure 1 is a vertical longitudinal section through an oil burner made in accordance with this invention, a portion of the block therof being left in elevation.

F ig. 2 is a horizontal longitudinal section of the oil burner.

Fig. 3 is a vertical cross section through the burner taken on line III-III of Fig. 1, and,

Fig. 4 is an end elevation of the oil burner on an enlarged scale and with one of the slotforming plates entirely removed.

Like reference characters referto similar.

parts throughout the several views and the numeral 6 designates the block of a burner made in accordance with the preferredform of this invention which may be cast of any suitable material to form an oil supply inlet 8 and a laterally extending pressure fluid supply inlet 10. As is the custom, ordinary fuel oil may be introduced to the burner through the inlet 8 and steam introduced through inlet 10. An oil supply passage 12 extends from inlet 8 the length of the burner to the outlets formed at one end of the burner block 6.

These outlets are in the form of radially eX- tending port holes 1 which pass through and terminate along the arcuate edge of the out wardly extending boss 16. The outer faces 18 of boss 16 are angled to converge as shown in Fig. l, in such a manner that they' approach each other as the arcuate edge of the boss 16 isapproached. As illustrated in Fig. 2, outlet port holes 14 are disposed radially and lie in fan shaped positions, each port hole 16 communicating with'the oil supply passage 12. A pair of pressure fluid supply passages 20 are formed within the burner block 6 and extend from the inlet to the outlet end of the burner.

Fig. 3 illustrates the manner in which the two passages join inlet 10. The outlet port holes 22 communicating with the end of each pressure fluid supply passage are likewise disposed on radial lines above and below outlet port holes 14. As illustrated in Figs. 1 and 2, the terminating ends of port holes 22 are disposed in an arcuate plane spaced rearwardly of the arcuate plane.

Back of and on each side of the outlet ends of port holes 14 are arcuate converging slots 24-. joined by the outlet ends of port holes 22. Deflecting plates 26 secured in place by bolts or analogous means 28, form the slots 24. be

tween the edges thereof and the faces 18 of boss 16. As shown in Fig. 1, port holes 22 join slots 24 and the steam or pressure fluid passing through port holes 22 will strike deflecting plates 26, spaced slightly forwardly therefrom and disposed at right angles thereto escape through slots 24 and be directed toward the outlet end of port holes 14. whereit will effectively join the fuel oil passing fromthe series of port holes 1 It will. be found that the action of these port holes will render the burner highly efiicient and since their radial position will spread the flame, it is obvious that any pie-determined area might be heated by slightly varying the degree of angularity. Through this construction steam is caused to pass outwardly from the outlet end of the burner entirely around the series of oil outlet port holes 14:. The end slots 80 join the upper and lower slots 24: to complete this point of advantage. Besides obtaining a nozzle eflect which causes the fuel oil and pressure fluid to leave the burner with greater force, port holes 14 and 22 tend to break up the fluids prior to complete atomization immediately in front of the port holes 14.

It is understood that modifications might be made in the structure oi oil burners embodying this invention and it is desired to be limited only by the scope of the appended claims. \Vhat is claimed and desired to be secured by Letters Patent is:

1. An oil burner comprising a block havin g a pressure fluid supply inlet, an oil supply inlet, a pair of pressure fluid passages and an oil supply passage formed within said. block extending from their respective inlets to outlets formed by said block, said outlets including a. series of radially extending pressure fluid ports and a series of radially extending oil outlet ports all formed in said block, and slots formed in said block on each side of the series of oil outlet ports, said series of pressure fluid ports communicating with said slots and positioned in a plane parallel the plane of said outlet ports.

2. In an oil burner, a block having a pair of pressure fluid supply passages and an oil supply passage formed therein, a series of radially extending port holes formed in said block, extending from each passage to form outlets, the port holes or": said oil supply passage terminating in an arcuate plane spaced forwardly from the arcuate terminating plane 01" said fluid supply port holes and a plate disposed in spaced relation to each of said sets of pressure fluid port holes to form covering slots above and below, respectively. said oil outlet port holes, said plates disposed at right angles to said pressure fluid port holes and spaced forwardly therefrom in an arcuate plane between the terminating planes of said pressure fluid ports and the oil outlet port holes, said oil supply port holes andsaid fluid supply port holes being in parallel planes and all converging to a common center line.

3. An oil. burner comprising a block hav ing a lateral pressure fluid supply inlet, an oil supply inlet, separate passages formed within said block continuing from each of said inlets respectively to outlets formed by said block, said outlets comprising a plurality or" radially extending ports, positioned in s aeed apart parallel planes, the outlet port-s oi the oil passage terminating in an arcuate plane spaced forwardly from the outlet ports of the fluid supply outlet ports and in a plane therebetween, and an arcuate deflecting plate between the outlet ends of said fluid supply ports and said oil outlet ports.

4:. In an oil burner, a block having a pair of pressure fluid supply passages and an oil supply passage formed therein, a series of radially extending port holes formed in said blockin communication with each of said passages, the series of oil supply port holes terminating in an arcuate plane forwardly of and between the pressure fluid supply port holes, and deflecting plates disposed in an arcuate plane between the outlet ends of said fluid supply port holes and said oil supply port holes, said plates extending across the fluid supply ports at right angles thereto and formed at their adjacent edges to converge toward the oil supply ports as their discharge end is approached.

In testimony whereof I hereunto affix my signature.
